i is illustrated in the accompanying drawings as follows Fig. 1 shows aperspective view of a corner of a window and screen with the hinge inplace.

Fig. 2 a section of a window frame with an edge View of the screen.

1 marks a window frame. This is pro vided with a guide face 2 and stop3.

A resilient hinge plate A is provided with a perforation 5 at its upperend through which extends a screw 6 to secure the plate to the frame andagainst the guide face 2.

The lower end of the plate is provided with a pin 7 which is adapted toextend into a perforation in a screen frame 8. A 11p 9 extends from theedge of the plate l and overlying the face of the screen frame. 7

l/Vith this structure the plate 4; may be secured on the window framebymeans of the screws 6. By swinging the plate outwardly from the plate,the frame may be flexed sufficiently to swing .the pin sidewisesufficlently to permit its passage over the edge of the screen frameinto register with the perforation in the screen frame. The pin thensnap ping into place in the screen frame permits the screen frame toswing back mto place on the window frame. It will be understood that theplates are arranged at each side of the screen. Fig. 1 shows a plate atone side of the screen and Fig. 2 a plate at the opposite edge of thescreen. The lip 9 extending over the face of the screen prevents theoutward movement of the screen incident to an outward movement of theupper rail of the 1927. Serial No. 187,167.

may be readily swung from the top and when it is desired to detach it,it is only necessary to swing it out a certain distance and flex theplate 4 sufficiently to withdraw the pin 7. It is only necessary to dothis 011 one side, the opposite side readily releasing itself with therelease of the one side.

l/Vhat we claim as new is 1. A hinge comprising a resilient plate havingmeans at one end for pivotally securing it to a support; means attheopposite end for securing it to a device to be supported, said meansbeing sufficiently remote from each other to permit the flexing of theintervening plate to detach the plate from the device supported; and alip at one edge adapted to overlie the face of the device supported.

2. A hinge comprising a resilient plate; means for pivotally securingthe plate to a support; a pin at the opposite end of the plate, said pinbeing sufliciently remote from the means to permit the flexing of theintervening plate to the extension of the length of the pin whereby itmay be detached through said flexure from a support and a lip at oneedge of the plate overlying a device to be supported.

8. The combination of a main frame; a swinging frame in the main frame;and a hinge at each side of the swinging frame comprising a resilientplate between the main frame and the edge of the swinging frame, saidplate being pivot-ally secured to the main frame and detachably securedto the edge of the swinging frame at a point sufficiently remote fromthe means of securing to the main frame to permit detachment by aflexing of the plate when the swinging frame is swung out of the planeof the main frame.

4:. The combination of a main frame; a swinging frame in the main frame;and a hinge at each side of the swinging frame comprising a resilientplate between the main frame and the edge of the swinging frame, saidplate being pivotally secured to the main frame and detachably securedto the edge of the swinging frame at a point sufiiciently remote fromthe means of securing to the main frame to permit detachment by aflexing of the plate When the swinging frame is swung out of the planeof the main frame and a lip at the edge of each plate overlying theswinging frame.

In testimony whereof We have hereunto set our hands.

THEODORE JOHNSON. PAUL G. JOHNSON.
